D. Rs. 42000
E. None of these
Answer: Option E
Solution(By Examveda Team)
Let Mr. More's monthly income be Rs. $$x$$Then,
[100 - (40 + 30)]% of [100 - 20 + 15]% of $$x$$ = 8775
⇒ 30% of 65% of $$x$$ = 8775
⇒ $$\left( {\frac{{30}}{{100}} \times \frac{{65}}{{100}} \times x} \right)$$ = 8775
⇒ $$\frac{39}{200}$$ $$x$$ = 8775
⇒ $$x$$ = $$\left( {\frac{{8775 \times 200}}{{39}}} \right)$$
⇒ $$x$$ = 45000
